APE1117A 1A LOW DROPOUT LINEAR REGULATOR FEATURES DESCRIPTION 1.5V Maximum Dropout at Full Load Current Fast Transient Response Output Current Limiting Built-in Thermal Shutdown Good Noise Rejection Need only 1uF Capacitor for Stability Low-ESR Ceramic Capacitor Required for Output Stability. APE1117A is a low dropout positive adjustable or fixed-mode regulator with minimum of 1A output current capability. The product is specifically designed to provide well-regulated supply for low voltage IC applications such as high-speed bus termination and low current 3.3V logic supply. APE1117A is also well suited for other applications such as VGA cards. APE1117A is guaranteed to have lower than 1.4V dropout at full load current making it ideal to provide well-regulated outputs of 1.25 to 5.0 with 6.4V to 12V input supply. 3-Terminal Adjustable or Fixed 1.5V, 1.8V, 2.5V, 3.3V, 5.0V Packages : SOT-223, TO-252, SOT-89.

Line and load regulation are measured at a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18" from the package. Note2: Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the difference between input and output differential and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range. Note3: Quiescent current is defined as the minimum output current required in maintaining regulation. At 12V input/output differential the device is guaranteed to regulate if the output current is greater than 10mA. 3 Advanced Power Electronics Corp. APE1117A PIN DESCRIPTIONS PIN SYMBOL ADJ/GND PIN DESCRIPTION A resistor divider from this pin to the VOUT pin and ground sets the output voltage. (Ground only for Fixed-Mode) VOUT The output of the regulator. A minimum of 1uF capacitor ( 10m < ESR < 1) must be connected from this pin to ground to insure stability. VIN The input pin of regulator. A minimum of 1uF capacitor is connected from this pin to ground to insure that the input voltage does not sag below the minimum dropout voltage during the load transient response. This pin must always be 1.5V higher than VOUT in order for the device to regulate properly.
